This adds the top for the Zero W. The geometry is garbage, but it works, TinkerCad doesnt really provide surface tools.

https://www.thingiverse.com/thing:4441076 presented a thumb screw to replace the wing nut on the front-left corner of the BIBO bed. It is too wide for the other two positions. I have created a smaller version to fit the right-front corner and the back-center.

A M3-.50 nut is required.

v2 Has the LED port moved to the correct location and I increased the size of the screw holes to M3's instead of M2.5's so you can use screws from common sets.
